. Bea known that i, ALEXANDER Meines- Y GALL, ak citizen of the United States, residing 'at Duluth,qin the county lof St.' Louis and State of `Minnesota,have invented certain .new and usefullmprovementsin Mining Ap' paratus,` of which` theV following is a'specific'a My inventi n relates tion, reference being had Atherein to the 'acto improvements in ,millingfapparatus,y and pertains more'partic# ularly to'hydra'ulicmining-machines. v The obj ect ofmyinvention is to provide a ..1 l machine of thischaracter in which provide the suction, end of the ipev used in Vmining with ai rotaryknife "or breaker which is located respect to the suction-pipe so that large'v pieces of 1 rock, clay, andthe like are yeither broken bythe knife or breaker belore :passing finto lthe suctionpipe or ,are forced, away by the same. I also provide`,'n combination with the rotary cutterorlbreake'r, a

strong jetv of'water 'adj acentl the same, which tendsto disintegrate the clay and rocks and fraise or suspend the same'in the water,where y bythe sand', clay, andstones are more readilygdrawn'intothe suction-pipe while in sus-vl Pensw Y r- Another object of my invention is to provide a machine of this ycharacter which is built upon la scow yof such a strength that-the ma-y chine canbe operated whether 'the scow is afloat'or not, andthe said scow is provided with'means whereby the same may be rigidly 4held in any'position While alloat and'in operation.A

i Vdepth than that shown in Fig. 1' and in which j erationin a mine, showing t In the accompanying drawings, Figuregl a sectional view of a'mine,'showing my machinetherein and in which the suction-pump.

upon the scow is forcing the ore tothe dump. Fig. 2 is a sectional view of a mine of a greater an 'additional pump is necessaryvto elevate the ore and water todum Figi is'an enlarged sidev elevation of t e a paratusin ope scow afloat therein.

Referring'now to the drawings, ly repre-A Patented .rune 19, 1906. i

i .flows the vwater vfrom the "dump, whereby the `same water is `used over land over again. lThe said reservoir'is provided with a water-supl .ply of some description, as there is a vcontinuedwaste of water' during the mining op'- eration, and thus the supply for the reservoir isv necessary.`

4My improvedl dredgev orniachine consists f of a scw 2, which is'mad'e' offa size to 4iioat the dredge and is yofvsuch a strength'as to withstand the strain to whichfdevices of this 'character are subjected, whether the same is 'afloat' Vorit is resting direc'tlyupon'thebote"` 'Y tom of vthe mine, whicheverl 'is' desired, or

fmore practical in different'kind's of mines or different .characters of 'ground in which the* spuds 6, which are adapted tol be driven into t located;V SCOW at eachend I .I j is `P'IOvided with downwardlyextendingv v e'bott'om'of thefminefa'nd hold the scow in'- y..

its set'position topr'e'vent .the same from'` .moving during lthe dredgingoperation. The

scow adjacent one end is provided with a suc-` tionfpump 7,1 Which is-driven by. a motor 8, carried by the opposite end of'the scow, andy the said pump has connected thereto a'leXie ble .pipe 9,. which extends downward from lone end of the scow andis providedy at its outer yend with a metal suction-head 10,'which is provided onzits `lower facewith the down-y ,wardly-extending studs` 11, which extend. a slightdistance in thesoft clay of the bottom of the mine and prevent'the 'same from Vmovmine, as will be hereinafter inore .fully described. The outer end offthe casingfhead l 104is open, and through which'the ore, clay,

and sand .is drawnlto thev suction-pump,vas

will behereinafter more fully described.

Theend of the scow carrying the pump is. j provided with an upwardly and outwardly extending derrick 13, rwhich. is pivotally mountedon the scow, the purpose of which will be hereinafter more fully described. The outer end of said derri'ck-is-provided with a block andtackle 14:,` the lower end of which is detachablyY secured to the suction-head 10 and by means of which the same is raised'and lowered during the movement offthe scow.

within the mine. outer end isprovided with ank upwardly-extending elongated lu v15, in which'is rotatalbly mounted the sha t 16, which is provided onits end with a rotary/cutter or breaker 17,

The head 10adjacent itsy IIO - versal connection 18, with la'shaft 19 carried:

' clay, andore and causes't-he Vsameyto be s'uswhich, as shown, rotates close to the outer open end of the suction-head 10, and :thusiy prevents large pieces of ore from passing into the pipe 9 and choking the same. xThesaid in which the same is to be used The shaft 16 extends inward and is provided with a'unif.l

by the scow, and thus the s'aidpropelleris frohead 10 is located. .The shaft 19 isdriven by any desired means such as an independent` motor, or maybe driven by the" motor 8, which drives the suctionpump. q

The suction-pump 7 is provided with' a dis-r'` charge-pipe 20, which. lhasconnected thereto` the upwardly-extendingA iiexible",pipe"j21, which extends out of thetmine to the'dump andthrough which the lore and water are con'- veyed to thedump. In Fig. 1 the'pump is of` suiIicient power to raise the water andoreto the dump; but when-themine has'become' too dee the power ofthe suctionpump v8 is not su 'cient to raise the ore and water to the dump, and in such a' case an .intermediate force-pump 22 is used to force :the water4 up to the'dump. When theminehasl become' still deeper, two or moreof these force-pumps- 22' are arranged in tandem'.

In order to supply themine withthenecessary water, I provide a suction-'pipe 23, which extends into the reservoir `5 andthe op-a.

posite end of said pipe isconnected toa suction-pump 24, which has'a dischargefpipe 25 extending down into-themine-1zThe lower' end 25 is carriedby theilramework4 of ther" scow and has connected theretoaliexblepipe--A 26, which extends down into 4the water adj a-'-' cent the casing-head andis provi-ded'with a'- nozzle 27, which, discharges jthe :water at one." side and adjacent-the casing-'head-,pzand'the force of the water disintegratesfthe;sand,
